IMPROVEMENT IN SELF-CORKING BOTTLES.

Specication forming part of Letters Patent No. 150,345, dated April 2S.1874; application filed January 5, 1874.

To all whom it may concern:

Be it known that we, HENRY MILLER and THOMAS MILLER, of the city ofPittsburg, State ot' Pennsylvania, have invented an Improvement inSelf-Oorking Bottles for Gaseous Liquors, of which the following is aspeciication:

Figure l is a vertical central section of the bottle, and Fig. 2 across-section on the line a' x of Fig. 1.

The invention relates to an improvement in soda and other self-stopperedbottles. Hitherto these have been provided with stoppers of sphericalform, and of such spccitic gravity'as to require the bottles to beinverted in order to be filled. In our invention the stopper is of lessspecific gravity than liquids, which adapts the bottlesto be filledwithout inversion. The neck ofthe bott-le is also constructed in apeculiar manner, conducing to strength,

and providing a suitable support for the stopper, when the contents havebeen discharged.

Referring to the drawing, O indicates the body, D the neck, and F themouth, ot the bot tle. The neck is enlarged to contain the tapered corkstopper E, but is suiiiciently narrow to prevent the same being reversedin po sition-t'. c., turned end for end.

Vhen the bottle is empty the cork rests on the bottom of the chamber,being supported by projections G. The latter are, preferably, four innumber, and are formed by bending the sides ofthe bottle inward, andthere are four corresponding or alternating vertical ribs orprojections, B, formed eXteriorly of the bottle, so that a cross-sectionthrough the contracted part presents the appearance of a quarterfoil,Fig. 2. The bottle is cast in a mold in the usual way.

In lling, the cork E will rise and close the mouth F so soon as theexterior pressure is removed.

To open a bottle thus stopped the cork is pressed downward with asuitable instrument, and the bottle quickly inverted. Unlike'thosebottles provided with the ordinary spherical stopper, the discharge ofits contents will continue unobstructed so long as the bottle is heldinverted, since the cork will then occupy the position shown in Fig. 1,owing to the pressure of the heavier liquid as it escapes at F.

The inner and outer projections G B impart great strengthI to the bottleat that point, and yet allow a free escape of the liquid into the neck,and the latter being enlarged o r bulged in its lower part correspondingto the form ot' the cork, there is little or no perceptible 0bstructionto the tlow.

We do not claim projections for supporting a stopper in the neck of abottle 5 but l. The combination of the inverted tapered cork E with thebottle, having a neck, D, ot' corresponding form, and contracted at itsj unction with the body O, as shown and described, to operate asspeciied.

2. The bottle having the inner and outer projections G B formed betweenthe neck and body by depressions in the sides, as shown and described.
